Was going to put this in Games, but Sudoku is more a logic puzzle. There are a lot of strategies for solving Sudodu, and I can do all the ones in the newspapers and mags. But the ones on the Net are much harder. Are there ones so hard that no solution can be found except to use brute number-crunching force (by computer) to get a solution?

All my friends are fantastic at sudoku and they LOVE it, but i don’t, mainly because well, I can’t solve those things. I just want to know for those sudoku solvers out there how do you solve them, is it natural ability, patience, or secret formula that I don’t know about…? Thanks.
